Trina Storage and TÜV NORD release white paper on energy storage safety
Trina Storage, the energy storage arm of Trinasolar, in collaboration with TÜV NORD, has published a detailed white paper addressing safety and reliability in energy storage systems. The paper explores market trends, safety challenges like thermal runaway, and mitigation strategies to ensure robust system performance. Key topics include intrinsic battery safety, structural and thermal management, and fire protection design. The white paper emphasizes rigorous testing (e.g., UL 1973, IEC 62619) and quality control systems to enhance reliability throughout the product lifecycle. The complete white paper can be downloaded here.
Last month, Trina Storage was ranked among the top 10 energy storage integrators in China, the UK, and Australia in S&P Global Commodity Insights’ 2024 Energy Storage System Integrator Report (see China Solar PV News Snippets).
Huasun delivers modules for offshore PV project
Heterojunction (HJT) solar manufacturer Huasun Energy has announced that it has started solar module deliveries for Phase I of the Qingdao Offshore Solar project being constructed by power developer POWERCHINA. Located in the Jimo District of Qingdao City, Shandong Province, the project has a planned capacity of 1GW (AC). Huasun says its Ocean modules, which use 210 x 105 mm cells and employ 20BB super busbar interconnect technology, effectively prevent microcrack issues during module transportation, installation, and use. It stated that the module samples passed TÜV SÜD’s 14,400-cycle vibration test without any microcracks. Additionally, the company claims the modules underwent 12-fold cyclic dynamic load tests and 6000Pa/3000Pa static load tests, with degradation rates of less than 0.5%, further validating the modules' superior performance in wind resistance and external force resilience, demonstrating high reliability and adaptability.
Huasun Energy recently won a 500 MW contract for HJT modules in China Huaneng Group's 2024 photovoltaic module procurement tender (see China Solar PV News Snippets).
DAS Solar’s flexible mounting system weathers Level-17 typhoon
DAS Solar has announced that its flexible mounting system installed at Hainan's 70 MW fishery PV project has endured Typhoon Yagi's level-17 winds. The company says TÜV Rheinland inspections confirmed the system’s durability, stability, and wind resistance, ensuring long-term project reliability. DAS Solar says the mounting system is designed for diverse applications, featuring pre-stressed cable structures to minimize deflection, mitigate wind-induced vibrations, and enhance torsional stiffness. It adds that rigorous testing has verified its ability to withstand extreme loads, including wind speeds of up to 46 m/s.
Recently, DAS Solar announced that it has retained its position on BloombergNEF’s Tier 1 PV Module Maker list for Q4 2024 (see China Solar PV News Snippets).
Trinasolar and Fudan University establish joint PV lab
Leading solar manufacturer Trinasolar and Fudan University have jointly unveiled the Trinasolar-Fudan University Advanced Photovoltaic Technology Joint Laboratory. This laboratory was jointly established by Trinasolar and Fudan University, one of China’s top universities. Through this collaboration, the lab will pool more research resources to promote the innovation and application of photovoltaic science and technology. It will also serve as an important platform for talent development, academic exchange, and collaboration, supporting high-level scientific research and a full-chain R&D paradigm, from basic research to applied solutions.
HIUV to build 80 million m2 solar film plant
Solar material manufacturer HIUV has announced plans to build a solar PV encapsulant film production base in Jintang County, Chengdu City, Sichuan Province. Upon completion, the project will have an annual production capacity of 80 million m2 of solar encapsulant films. The project is estimated to cost approximately RMB 250 million ($34.3 million). The company plans to fund the project through its own funds, direct or indirect financing. The project is expected to be operational within 8 months of the completion of its factory building.
Risen promotes copper paste for HJT solar cells
Solar panel manufacturer Risen Energy has announced progress in the testing and mass production of copper paste in its heterojunction (HJT) solar cell production line. The company stated that, while ensuring cell efficiency, using copper paste in HJT production can reduce the consumption of pure silver in each Watt of solar cell output from 6 mg/W to 0.5 mg/W. Risen Energy's research team has found that a 10 nm thick TCO layer on the silicon wafer surface effectively blocks the penetration of copper ions at temperatures below 650°C. Since the TCO layer is a barrier, copper ions are less likely to diffuse into the cell, and HJT cells are processed at a low temperature (not exceeding 200°C), making HJT technology highly suitable for copper paste materials and processes. Risen Energy further stated that the application of pure copper paste in HJT solar cell manufacturing can be achieved without major modifications to existing production lines.
